Johns is currently writing the 'The Curse of Shazam!' back-up feature, which will run in DC's Justice League from issue #7. According to the scribe, the strip is tonally similar to the work he has completed on the movie.

"It's got some elements that I pitched in there, and some of the same characters, obviously, because the characters cross over," he added. "Tonally, it's probably pretty close."

Shazam! tells the story of teenager Billy Batson, who is granted a special ability by the wizard Shazam that transforms him into a superpowered adult.
